Existing Sites:

Carr: New receiver firmware was installed on July 10, 1994 to support 3.0
      beta testing

Gode: RF configuration change. Gode's Turbo rogue SNR values have been
      low due to a RF splitter with high loss / low isolation. On 7/18/94
      the RF splitter was removed.

Mcmu: Frequency standard switched from rubidium to internal. 
      ( Mcmu  reference was swapped on  July 18, 1994 to support site
      troubleshooting . Please see IGS message # 678 )

NLib: The defective RF helix cable has been replaced  as of 7/11/94
      The site is now operational

Quin: The GPS antenna is back on top of monument 7221 and the site is 
      operational.
      The antenna was removed on 7/12/94 at 14:00 ut and replaced on 
      7/16/94 at 00 ut. Please see IGS message # 679


New Sites:

Nasa/JPL has installed two new sites to support NASA's commitment to the  
Southern California GPS Array project. NASA's plans to install 13 more
